We are currently running Exchange 2007 on an SBS2008 single server. We are having trouble with one of our clients running Outlook 2007, in as much as it keeps asking for a username and password for "Remote" and "SBS2008". We have tried all, but the only way we have found to use Outlook is to click on the cancel button.
Having researched this, I understand that if we install rollup9 or SP2, this should resolve the issue.
This raises a few issues.
Having checked exchange server configurator it states that we are running Version 8.1 build 240.6 with no mention of a service pack at all. Does this mean we do not have any service packs installed, or am I looking in the wrong place.
If we do not have a service pack installed, are we best installing Service Pack 3 now, and do we need to install SP1 and SP2 before we install SP3.
At nearly 900mb, this is some service pack. Can I assume that it is OK to install these on a currenty configured and working exchange server? ie can I presume it will not wipe all of our current users information.
Any advice would be much appreciated.
